i would say go with the LED soldering. it's probably the best way, but even I would take the spray paint way myself if I were lazy or needed to see how a quick and easy job would turn out. If you don't like it then get the iron, solder, and LEDs ready. it's quite expensive i believe.
and some guys on the TL board have done all their whole dash in LEDs. nate was the first and believe me, the TL has A LOT more LEDs to solder than the accord.
